Water Quality Monitoring

Water quality is a primary area of focus for the Lake Zoar Authority. The LZA performs regular water testing for eColi and other conditions at several locations throughout the lake. The results are sent to the four member towns and the appropriate health departments. The towns and/or DEP also test water at public beaches.

 

The LZA’s role is information gathering. The LZA also participates in water studies to learn more about the changing conditions of the water. In addition to quality, the LZA has an extensive program to control the growth of invasive weeds and as funds allow the most infested areas are treated with an herbicide that is used in over 150 lakes in CT each year.

 

Submitted herein are test results and survey reports for public interest.
